Unbelievable Photos That Were Declassified by the CIA

Graf Zeppelin

This is a photo of a German airship over Washington DC. This is the Graf Zeppelin, not to be confused with the Hindenburg made by the same company. This ship floated over the nation's capital with no warning, so naturally, chaos ensued and civilians thought that someone was attacking them. They had not even seen something of this stature at that point. This photo was taken in 1928.
